Ouroboros

Ouroboros is an open-source, general-purpose AI agent whose identity, durable memory, and history continue across tasks and restarts. It works on external projects, coordinates a live swarm of specialist agents, and can rewrite the implementation it runs on, including its code, architecture, prompts, tools, and dependencies. Reflection can also change how it understands itself without severing that continuity.

It runs as a native desktop app or through a headless CLI. The runtime keeps its repository, durable memory, history, and interface on your machine, while model inference can use remote APIs you configure or a local GGUF model.

Ouroboros sends no telemetry by default, and the official project operates no usage or crash-report collection. A deployment can connect its own monitoring tools to its local records and choose what they receive; local history stays on the machine either way. Requests through OpenRouter carry the app name, which OpenRouter uses for its public app statistics.

Changing Ouroboros? Coding agents and people must read CONTRIBUTING.md before editing. It defines the required project context, verification, and separate-agent review flow.
